Overall Depth Range in Sargasso Sea: 0-2000 m (Deevey & Brooks, 1977, Station "S"). 446-719 m at Station S 2 in S Bösö (E middle Japan). 234-3010 m at Station T-1 (E Tori Is., E middle Japan) from Furuhashi (1966 a).
The geographical distribution of this species needs confirmations, notably in the Arctic seas where it could be confused with N. polaris.
For Boxshall (1979, p.258) the segmentation of P1 is rather variable with endopod being either 2-segmented (Giesbrecht, 1891, 1892) or 3-segmented (Sars, 1900; Wolfenden, 1905); this variation appears to reflect merely the degree of separation of the two distal segments and is not regarded as significant (Farran, 1905).
Ivanenko & Defaye (2006, p.722) indicate the type species was originally described as Mormonilla minor Giesbrecht (1891, 1892) from the tropical part of the Pacific Ocean, and the redescription was based on specimens from the northeastern Atlantic (Boxshall, 1979; Huys & Boxshall, 1991). Farran (1908) synonymized Mormonilla atlantica Wolfenden (1905), lacking illustrations, with Mormonilla minor. Further re-examination of mormonillids from the type locality (3°S, 99°W) and comparison with mormonillids from the northeastern Atlantic are necessary to confirm the identity of copepods from the two oceans.
Fierro & al. (2016) note the first record of this species off north Chilean coast, found > 100 m depth associated with oxygen minimum zones and temperatures below 10*C. Any discordance with the morphological description of N. minor by Ivanenko & Defaye (2006), would indicate that further investigation into the variability of the species is required.
After Benedetti & al. (2018, p.1, Fig.2) this species belonging to the functional group 7 corresponding to small filter feeding herbivorous. | | | Last update : 07/12/2020 | |
